The final mission. This is a going to be a long one so prepare yourself. Within moments of the level beginning, your base will be assaulted be a small force. Kerrigan can clean this up and after doing so make sure to begin building up your base. You will need plenty of drones for this as there is plenty of room to lay a defense and build structures. No one unit is going to be the run away hit for this mission, so build up the army of your choice. If you want to have a bit of a laugh, use Banelings in your primary force. The enemy bases tend to be very spread out, so Banelings can weave through everything causing massive amounts of destruction, at the downside of not being able to hit air.

As early as possible, head to the right and claim your expansion. It will come under attack regularly so station units there to defend it. Hydralisks work best for defense on this map as the enemies will often employ Banshees in their army. About 5 minutes into the level, the Hyperion will show up. They will set up a small base near yours and slowly chip away at your enemy. Sadly, Mengsk does not like this and will routinely send forces to kill them. Although Jim's forces are tough, they will need help. When you have the units available, station about 15-20 Hydralisks over there to assist him. Mutalisks will also work fine, the important thing is that it is a unit that can attack land and air.

To claim the bonus objectives, you will need an army, so don't bother going for them until you have one. What you can do in the mean time is chip away at the enemy with Kerrigan. Any one of her ultimate abilities will allow you to do so, but we found Drop Pod to be the most useful. It will give you a bunch of free units and any upgrades you have for your own troops get applied to these ones, so once you reach 3/3 upgrades you will have quite the wrecking crew. After claiming each bonus objective, go back to base and regroup and rebuild your army before setting out again.

When it comes time for the final assault, make sure you have 200/200 population. If you have whittled away Mengsk's forces then all that should remain are the ones located in and around his last base. This place is pretty heavily fortified, so make sure the units leading the charge can absorb the blows. Having some Infestors with you can also make things more interesting. Using Parasite to steal some of the super Thors can really turn the tide of battle. If you find the final battle is going in the enemies favor, don't be afraid to pull out, rebuild and try again. So long as you did some damage, your next attack will likely be successful. Destroy the wall to complete the mission and Sc2 Heart of the Swarm.

Tips - This one can be a little tricky due to how unreliable Jim can be. Sometimes he can go entire missions with no help and take 0 damage. Other times he gets completely steam rolled. The safest thing to do is to station 15-20 units over at his base to help defend him. This in conjunction with his own units will keep him safe and get you the achievement.

The easiest way I have found to get this achievement is to send about 10 Hydralisks initially along some Infestors over to Raynor’s base. I have found 3 to be ideal. Park them there with an Ultralisk; just for them to suck the life out of. Don’t worry, Jim’s Medics/Medical will heal the Ultralisk while you steal the Banshees, Battle Cruisers, Black Hammers; whatever your desire. Park the Battle Cruisers right next to Raynor’s base. Nothing will get by them and Jim’s forces. The Odin won’t even get close. Btw the Odin can't be infested. The end result; nobody will lay a finger on the Hyperion.

Tips - 25 minutes is a tough number to aim for. The most important part of this will be Kerrigan. You will need to use her well, and push as far as you can with her during the time you are building up your forces. To help build out your army quicker, claim the second base quickly and build a third Hatchery so you have extra larvae. For units, you will want to use a healthy mix of everything. Zerglings, Hydralisks and Aberations are great during this. Ultralisks can also serve you well here but are a little more costly to build. When leading your forces out, have the Aberations out front so they can absorb incoming damage. Make sure to spam Kerrigan's Heal as often as possible. To speed things along, don't waste any time clearing out unnecessary enemies. Only cut yourself a path directly the Palace Gate. The 15 minute mark is when you should make your first attempt. It is likely you will not clear out everything in this one go but ideally you will clear everything up to the gate. By the 20 minute mark you should have your army rebuilt and ready to go again. Go out again and push on to your goal. If you have cleared out the enemy enough, you can simply focus fire the gate and ignore the units that may be attacking you.
